| 35 | Folding super chair | US12178774 | 2008-07-24 | US07607733B1 | 2009-10-27 | Mei Chuen Lin; Tzu Mei Wang |
| A folding super chair includes a front leg frame, a backrest, a backrest frame and a ganging device. The backrest frame has a contour corresponding to an upper inner portion of the front leg frame and an L-shaped cross section. The backrest frame is disposed between the front leg frame and the backrest. The backrest is placed on the backrest frame, which relieve stress. Thus, a ridge of the backrest does not deform, and the backrest is securely fixed on the folding super chair. The ganging device includes a main member, a slot fastener and a knob fastener. The main member has a front face, a rear face and two side faces. The rear face is larger than the front face, and therefore the two side faces form an included angle therebetween. When the folding super chairs are lined up and connected by the ganging device, the folding super chairs form a curved row. | ||||||

| A leg frame of a chair having a decoration strip engaged therein includes the leg frame and the decoration strip. The leg frame includes a frame base, two curved ridges respectively disposed at both edges of the frame base, and an engaging groove formed between the frame base and the curved ridges. An inner lower side of each curved ridge is slanted to form an acute corner between the frame base and the curved ridge. The decoration strip corresponding to the engaging groove is fitted in the engaging groove. The decoration strip includes a bottom surface, two concave side surfaces, and two extended ribs respectively disposed between the bottom surface and the side surfaces. When the decoration strip is engaged with the leg frame, the ribs are respectively engaged with the acute corners and the side surfaces are respectively in contact with the curved ridges. | ||||||

| A folding chair having a novel hinge and joint surface configuration that forms a substantially rigid structure approximating conventional non-folding chair designs. In one embodiment, the present invention provides a folding chair comprising a seat frame, a backrest frame hinged proximally to the rear edge of the seat frame and forwardly collapsible over the upper surface of the seat frame, and back legs hinged to the rear edge of the seat frame and forwardly collapsible over the lower surface of the seat frame. The chair, in one embodiment, further comprises front legs hinged to the seat frame and collapsible over the back legs. In an assembled state, the back legs and the backrest frame each abut against elements of the chair at joint surfaces, which limit the range of motion of the hinged members to thereby create a chair having a rigid support structure. In one embodiment, the seat frame, backrest frame, and back legs unfold into an interlocked configuration enhancing the stability of the chair. | ||||||

| There is provided a portable, folding chair with an enhanced seat and backrest. The seat includes a suspension system that is capable of providing an enhanced range of motion in seating directions. The backrest provides enhanced support through an enlarged support surface and improved disposition of the support surface relative to the chair frame. The seat and backrest can be used together on the same chair or independently. There is also provided an alternate seat employing a suspension system that is capable of providing an enhanced range of motion in seating directions and that has a low profile to be used in situations where storage space is a significant consideration. | ||||||
